It's stupid in that the 2% AUM is completely random, namely it can be anywhere on the chart. What if it's just above the trendline or support/resistance? In that case, it will surely get hit and you'll be stopped out. It would be much better to place it under the trendline even if it's more than your average 2% rule.
Bruh, your % risk will be fixed regardless of where you place your stop. I think you're confusing % price move with actual risk
